quick nuites qustion

I am 4th week into flowering . And think got deficiencies. I want to use epsom salts . So can I just add a 1/4 teaspoon to the water bottle I got nuties in . Or do I have to water in seprate bottles .

that sounds like a lot of epsom salts, though i guess it depends on the bottle size
magnesium deficiency is possible, some kind of PH issue is more likely

My ph is 6.5./6.7 . How much salts should I put in a 3 liter bottle . The leaves. R yellowing. The whole leave not just the edges and a. Lot r falling off . So I though it could be mag deficiencies

it's a bit quick, but some strains do start their yellowing of fans early
maybe more of a limit of nitrogen, the buds are sucking the N out of the fans(and probably other nutrients)
but a picture will get more participants
